Used for a little over a year. There are no dents or scratches of any kind. A cover and protector have always been used, so it looks shiny like new. The best part is that the battery backup is still very great. After charging to 100% and unplugging, using it for 20 minutes drops the charge by no more than 5%. There are no servicing issues. No problems at all. You will get a 15-day replacement guarantee.
